Why the Celtics can cover

Boston has five players averaging 13 or more points per game, including three averaging at least 20 points. Among them is eighth-year veteran center Kristaps Porzingis, who is averaging 20.2 points, 6.9 rebounds, 1.9 assists and 1.8 blocks in 29.6 minutes. He scored 23 points and grabbed 12 rebounds in Tuesday's 117-99 win over Philadelphia, his eighth double-double of the year and 122nd of his career. He had 22 points, four assists and four rebounds in a 116-102 win at New York on Feb. 24.

Point guard Jrue Holiday is coming off a 13-point, seven-rebound and four-assist effort in the win over Philadelphia. Holiday has scored 10 or more points 38 times this year, including seven games with 20 or more. He has seven double-doubles in 2023-24 and has 154 double-doubles in his 15-year career. In 53 games, all starts, he is averaging 13 points, 5.7 rebounds and 4.8 assists in 33.3 minutes of action. See who to back at SportsLine

Why the Mavericks can cover

Point guard Luka Doncic is questionable with an ankle sprain and broken nose. If the team's leading scorer at 34.4 points per game can't go, look for point guard Kyrie Irving to play an even more prominent role for Dallas. In 37 games, all starts, Irving is averaging 25.9 points, 5.2 assists, 5.1 rebounds and 1.3 steals in 34.1 minutes of action. He is coming off a 29-point performance in a 136-125 win at Toronto on Wednesday, and has scored at least 29 points in each of his last five games.

Power forward PJ Washington, who was acquired in early February from Charlotte, had his best game as a Maverick in Wednesday's game. In 31 minutes of action, Washington poured in 23 points, while grabbing six rebounds and adding three blocks. In 51 games between Charlotte and Dallas, he has made 23 starts, and is averaging 13.2 points, 5.3 rebounds and 2.1 assists in 29.5 minutes. He has faced Boston once this season, scoring 15 points and adding two steals. See who to back at SportsLine
